Another ARP issue

Hello All!

I have an FCX 648 with running routing software 7202e. I have turned on

debug ip arp

and found the following:

Debug: Feb 28 14:19:45 next hop router 10.0.41.4 ARP mapping deleted
Debug: Feb 28 14:19:45 next hop router 10.0.41.5 ARP mapping deleted

...

Debug: Feb 28 14:19:47 next hop router 10.0.41.4 ARP mapping deleted
Debug: Feb 28 14:19:47 next hop router 10.0.41.5 ARP mapping deleted

...

Debug: Feb 28 14:19:49 next hop router 10.0.41.4 ARP mapping deleted
Debug: Feb 28 14:19:49 next hop router 10.0.41.5 ARP mapping deleted

...

It deletes mappings to next hops in every two seconds! This gives enough time to drop packets to 10.0.41.4 and 10.0.41.5! The drops stop, when I add static ARP entries for the next hops. Is there a way to solve this problem without adding the static ARP entries?

Thank you if you answer.

Re: Another ARP issue

Don't see an obviously relevant bugfix but wonder if 7202f is worth a try...released last week.
